IMPROVED DRliLLlNG-MACHINES.

Specification forming y: rt of Letters .Patent No. 58,175, dated September 18, 1866.

To all whom it may concern:

Be it known that I, ROBERT NUTTY, of the city, county, and State of New York, have invented new and useful Improvementsin Drilling-Machines, and I do hereby declare that the following is a fullclear, andeXact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

Asis well known, the chief and most important expense in quarrying is the boring of the holes necessary for` `the insertion ot' the charge, and when the rock `is very hard this is not only a slow and tedious operation, but also very expensive, thereby rendering nany practical contrivance or machine for facilitating it or for abridging the time requiredfor its performance very desirable and of decided importance and advantage.

To produce a machine for quarrying' purposes, more especially by means ot-whiclr the holes for the blasting-charges could-be drilled, has long been desired, and inthose machines which have heretofore been experimentedwith and used in and for quarrying, owing to the continual and irregular change and variation in the face of the quarry, `occasioned by the blasting,the greatest difliculty has been `experienced in properly brin ging the drill or drills used to bear` against the faceof the quarry, inv many cases it being impossible to obtain the desired adjustment of the drill, and consequently rendering` the machine attimes, and in the majority ofcases, useless andof no avail, the advantages gained by such machines hardly compensating for their cost andthe trouble and annoyance experienced in their use and operation.

In the machine embraced in the present invention the drill or drills are so. hung and ar-` ranged that, whether to operate or work against the face of the quarry or rock in a vertical, horiraontal, or` in any plane between the two, it can be readily adjusted and brought to the proper position therefor, and when in'any of such positions be operated'in the desired manner, as` will be obvious from the following detailed description of the machine, as well as of the manner in which it is used, the drillingmachine being adapted to any and allfspecies of rock-work, in addition to quarrying-such, for instance, as tunneling, mining, sewering, and submarine drilling. y

In accompanying plate of drawings my improved drilling-machine is illustrated.

A in the drawings represents the platform of the machine, which is supported upon four or more Wheels., B, like the platform of an ordinary railway-camand is to be of suitable shape and size to sustain the various working parts and frame-work of the drilling-machine, which are to be soon explained; B2 B2, the framework of the machine, the lower portion of which consists of a circular disk, C, to the upper side of which is secured a platform or table, D, having fixed or attached to its upper side a raised: annular ring-flange, E, having an` annularslotted ring, F, with tie or link pieces at suitable points of its slot; H, a circular disk, placed above the slotted annular ring F, and in a plane parallel therewith, which disk at its centeris secured to a center vertical shaft or mast, G, passing down through the lower parts of the frame-work into suitable bearings of the platform A; The disk H has a slot, I, extending entirely around it, which slot is in a corresponding vertical plane t'o the slotted ring F, and both' are at all points at equal distances from the center shaft or mast, G, or, in other words, concentric therewit-h. Between the slotted ring F and disk H are uprights J, at suitable distances apart to sufficiently brace and support the upper disk, H, which upright-s are arranged by the pins a of their two ends in the slots of the said disk and ring, thus enabling them to be moved around upon the same and brought to any desired point thereof, where, by screwnuts b, or other suitable means, they may be 2 sans v securely fastened. K, a boom or arm, that by means of a clamp, L, at one end is secured to the center mast or shaft, G, between the disk H and platform, and, extending in a radial line, is hung, by a bolt, c, passing through it, to one of the uprights J, beyond which it projects. and has hungto its outer end, M, a drillrod, N, the peculiar arrangement and manner of operating which will be now described.

O is a plate placed upon the upper side of the boom K, where it is held by means of bolt-hooks P passing through the same and around the bars Q of the boom by their hook ends, on which bolts nuts d are screwed, firmly and tightly binding the plate to the boom. The central portion, R, of the plate O is cut ont, and through it loosely pass two vertical screwrods, S S, that upon their upper ends, have screw-nuts T2, and in the eyes U of their lower ends (see Fig. 4) have hung the trunnionpins V of a frame or yoke, W, in the arms X, upon the lower side of which the upper end of a steam-piston cylinder, Y, is suspended by its trunuion-pins Z Z upon opposite sides of the cylinder, and at points diametrica-lly opposite each other, the said yoke or frame W and piston-cylinder swinging in planes at right angles to each other.

To the lower head, A2, of the piston-cylinder a vertical frame, C2, is secured, consisting of two parallel uprights, D2, and end piece or bar F2, between which uprights is arranged a sliding head, E2, so as to move and slide upon the same; G2, a hollow piston -rod or tube passing up through the center of the pistoncylinder and each head of the same, to which rod the piston-head is secured, as in ordinary piston-cylinders of steam or other engines. This rod G2 at its lower end is secured to the sliding head E2, so that as the rod is moved up and down by the action of the steam admitted to lthe piston-cylinder in any proper manner, the sliding head will also be carried up and down with it, playing upon the guidebars ot' the frame G2.

Through the center of the rod G2 the drillrod N is passed, and down through the sliding head E2, in which, by its screw-threaded portion, it screws, and from thence down loosely through the cross-bar F2 ofthe frame G2, hereinbefore referred to, with a socket in its lower end suitable for receiving a drill.

The drill-rod N is made of a square or other suitable shape, and has a loose small bevelpinion wheel, H2, through which the rod can loosely play, but yet be turned by it as it is uprights D2, which frame, upon one side, is engaged with the arm 02 of the sliding crosshead E2, so that as such cross-head moves up and down the frame will spring upon the uprights D2, to which it is hung, and thus move the spindle or shaft P2 into or out of the valve seat or box Q2, attached to one side of the piston-cylinder.

From the above description of the manner in which the pistoncylinder is hung in and to the outer end of the boom, it is plainly apparent that it can be swung into any desired position with regard thereto, and also either raised or lowered at pleasure, and there secured by adjusting the suspension chains or wires R2, extending from the plate of the boom to the lower end or head-plate of the pistoncylinder; and, furthermore, the position of the piston-cylinder on the boom may be changed at pleasure by simply loosening the nuts that hold the plate in which it is hung to the boom and then sliding such plate along and upon the boom until, having brought it to the desired position,it is there secured by tightening the said nuts, thus causing the bolt-hooks to lirmly grasp the side bars constituting the boom.

As the piston-cylinder is thus susceptible of being swung and brought to various positions upon the boom to which it is hung, it is obvious, if a connection between the cylinder and a steam -generating apparatus be made, that will admit of such chan ge in position and adjustment of the cylinder-as, for instance, through a tieXible conducting pipe or tubethat the drill-rod can be made to move or act against the face ot' the quarry in any desired direction, whether in a vertical or horizontal plane, or in any plane between the two, according as it may be necessary to accommodate it to the direction or course of the layers or laminze of the rock; and that, furthermore, if the clamp by which the boom is clamped to the center mast or shaft be loosened, as well as the upright to which the boom is hung, the boom can be swung around upon the framework of the machine, so that its drill can be brought into position to operate against the side of the quarry, whether to the right or left, the importance of which is obvious.

Y In lieu of using steam as the motive power for the drill, atmospheric air may be employed,

or any other suitable motor, and therefore I do not intend to limit myself to any particular power to be used, so long as that power is communicated toor connected with the drill in any suitable manner that will permit the drill to be adjusted in position, as above explained, and yet be operated thereby;

Although only one boom with its drill has been described as connected with the center mast of the machine, it is obvious that more than one may be employed and arranged within the frame-work ofthe machine, so that any desired number of drills may be working oriny operation at one and the same time.

As the drill-rod is operated by the forward and backward play of the piston within its cylinder, it is partially rotated upon each stroke by the action of the spring vhook or pawl L2 attached to the sliding cross-head E2 upon the ratchet-pinion l2, interlocked or engaged with the bevel-pinion wheelon the drillrod,the object of which is to cause the drill to properly act upon the rock to drill a perfectly round hole therein.

It may be here remarked that it is plainly obvious from a close examination of the turning motion of the drill that the hole produced by it must be perfectly round, and with no projections or depressions, as are left by all drills if turned irregularly, such projections and depressions being in most cases'the principal cause of the drill breaking; and, furthermore, to alter the speed at which the drill is turned, it is only necessary to raise or lower the spring hook or pawl L2, attached to the cross-head E2, the spr-in g for this purpose being secured to'the said cross-head by a slot and set-screw, or in any other suitable manner therefor.

In order to increase the efliciency of themachine two or more tiers of drills may be arranged one above another; but I do not think more than two tiers will be required or rendered .necessary for ordinary quarry work.` In addition to the boom or arm of the machine carrying a drill which is arranged to be worked by steam, air, or other similar power, I have similarly hung another boom or arm, A4, to the frame-work, on which boom a drillrod, B4, is hung, as will be 110W described, as well as the manner in which itis operated.

C4 is a platform, placed just above the main platform of the machine,turning upon the center mast or sha-ft, G. To this platform are secured two upright frames; D4 D4, across which extends a horizontal shaft, E4, turning in bearings of each'of the same. On one end of this shaft E4 is a crank-handle,F4, for convenience in turning it, and on its otherenda wheel, G4, having a series of teeth, H4, that in turn, acting against theinner end, I, of a lever or beam, J4, hung upon afulcrum at K4 of the platform C4, depresses such end of the beam, consequently lifting its outer end and the drill-rod` B4, hung by its trunnion-pins a4 in the slotted arms or ends of the beam, when, the wheeltooth having passed by the beam J4, the outer end of the beam then falls by its own weight, bringing the drill to bear aga-inst the rock that is to be drilled, the play of the beam in a downward direction being' limited by the frame L4, secured to the boom. j

To rotate the drill-rod as it either moves up or down, or both, I have pivoted to the walking beam or lever J4 one end of a connecting bar or rod, M4, the other end of which is hun gl to one arm, N4, of a double-crank shaft, O4, turning in bearings of the boom, the arm P4 of which is connected through a rod, Q4, upon the upper side of the boom to the crank-arm R4, hung upon a loose collar, S4, upon the square portion of the drill-rod. To the under side of this crank-arm R4 a Aspring-pawl is hun g that engages with the ratchet-teeth U4, formed aroundthe loose collar S4, hereinbefore referred to, which pawl, through the movement of the parts connecting it with the walking beam, rotates the ratchet wheel, and through it the drill-rod, each time the said beam is raised and drops or falls, as hereinbefore explained. This boom or arm, having th e. drill-rod B4 hung in it, as` above described, is susceptible of being moved about and around in the frame-work of the machine, and brought either to the right or left and front or rear side of the same, according as may be necessary for the operation of the drill against the rock of the quarry.`

To the under side ofthe outer endof each boom an arm, L5, is hungby its elongated slot M5 over and upon a square-headed pin or stud, N5, one end of which arm is made or prov-ided with two forks or prongs, 05, and to the other a long lever or bar, P5, is pivoted, the use of this pronged or forked arm and bar P5 hung to it being for-and as a means of bracing the boom in position as the drill of the boom is worked or operated.

'In the use of the drilling-machine hereinabove explained, it is intended to place the engine from which the-power is transmitted Vto the drill through iiexible connecting .pipes or tubes upon the platform of the machine, so. that the whole can be run out of and away vfrom or into the quarry, according as may be drills, as is obvious by an inspection of the drawings. i

With slight changes or modifications in the machine, it can be adapted to various styles of rock work, such as tunneling, sewering, submarine work, &c., as well as to drilling in a quarry, and therefore I do not intend to limit myself to any one particular use or purpose to which it may be applied or be adaptable, the present invention principally consisting in hanging the drills in sucha manner to the boom and in so operating it that whether working in a horizontal or vertical plane, or in a plane between the two, it can be brought to bear against the rock: or quarry in a proper manner to drill the same. t

It maybe hereremarked that bymeans of the screw-thread upon the drill-rod, in eachcase, the drill-rod, as it is turned by the action of the devices arranged therefor, is necessarily fed downward as fast as the hole is drilled in the rock, so that when the desired depth. has been reached to run the drill back or out of the hole, a bevel pinion-Wheel, S5, is hung byits spindle'l5 in one of the side pieces, D2, in proper position for meshing with the bevel-gear or pinion H2 upon the drill-rod, whereby by turning the said pinion S5 through the crank-handle U5 of its spindle in the proper direction the drillrod can be raised or lii'ted and brought back to its original position, as is obvious Without any further explanation.

What I claim as new, and desire to secure by Letters Patent, is-

l. The piston-cylinder of a steam, atmospheric, or other suitable engine, with the piston of which a drill-rod is suitably connected, so hung that it can be adjusted to enable the drill to 'be brought to bear against the surface of the roel; orother surfacev to be drilled in any desired direction, whether in a vertical or horizontal plane, or in any intermediate plane, substantially as described.

2. A piston-cylinder through which a drillrod is operated, hung upon the boom or supporting-beam.therefor in such a manner that it can be moved thereon and set at any desired position', according to the point of the rock or other surface against which the drill is to -act, substantially as and for the purpose described.

3. The pronged lever L4, hung to the outer end of the drill-boom, and having an extensionarm,-P5, swiveled or pivoted to it, substantially as described, and for the purpose specified.

4. The piston-cylinder hun g by trunnionpins to and in a frame, W, that by trunnionpins is suspended in the eyes of screw-rods S, having screw-nuts T2, said screw-rods passing loosely through the boom K, orits equivalent, substantially as and for the purposes set forth.

5. The extension-frame C1, secured to the bot-torn of the piston-cylinder, in which frame slides a cross-head, E2, carrying the drill-rod N, and connected with the piston-head of the cylinder, in connection with which it moves, substantially as and for-the purpose described.

6. The arrangement of the bevel-pinion H2 on the drill-rod, ratchet-pinion I2, hung in stationary bearings of the frame C2, and springpawl L2, secured to sliding cross-head E2, when arranged and connected together so' as to operate upon the drillrod as the cross head moves forward and backward, substantially as described, and for the purpose specified.

7. The tappet-Wheel G4, walking-beam J4, having drill-rod B4 suspended in its outer end, connecting link or piece M, double-crank shaft 04, rod Q4, connected with crank arm S4, carrying apaivl, which engages with the ratchetwheel U4 of the said drill-rod B4, when the several parts are combined and arranged together so as to operate upon the drill-rod, substantially in the manner and for the purpose described.

8. The arrangeinent'and construction of the frame-Work of the machine, the same consisting of the parallel horizontal slotted platforms D and H, connected to a common center-post, G, and supported at suitable points by uprights-J, for holding the drill-booms, the Whole being supported upon suitable Wheels or friction-rollers, and arranged and connected together substantially in the manner described, and for the purpose specified.
